In nonrelativistic Coulomb plasmas with quantum dynamics and statistics,
the effect of
an external uniform magnetic field upon thermodynamics and the algebraic
tails of position
correlations is discussed. The results are obtained in the framework of a
path integral
formalism. The exact virial expansion of the free-energy density at finite
temperature is
calculated up to order 
in the density ρ. It exhibits the
interplay of
Coulomb interactions and quantum statistics with bare diamagnetism and
paramagnetism.
Moreover, the static particle correlations are shown to decay as 
at
large
distances r, and the exact analytical coefficients of these tails are
given at first order
in ρ.
